Bacteria are also able to communicate with each other through chemical signals, a behavior known as quorum signaling (QS). These chemical signals spread through a biofilm that colonies of bacteria form after they reach a certain density, and are used to help the colonies scavenge food, as well as defend against threats, like antibiotics. Researchers examined how different structures affects biofilm growth and QS by the bacteria in the presence of antibiotics. They found structure does have an effect on QS in some strains of the bacteria.

Researchers developed a computational approach to predict which metal-organic framework (MOF) structures will be the most stable, and therefore the best candidates for applications such as capturing greenhouse gases.

What defines the habitat -- the ecological niche -- of a microorganism? It is a combination of environmental factors such as temperature, moisture, and nutrient content. But the exact contribution of each of these factors is difficult to predict. A research team has redefined microbial niches by determining which microorganisms live together.

A team has induced stem cells to emulate the development of the human heart. The result is a sort of 'mini-heart' known as an organoid. It will permit the study of the earliest development phase of our heart and facilitate research on diseases.

With dengue on the spread, the new discovery helps explain why dengue viruses are so easily transmitted. The finding could also lead to new ways to prevent infection.

Chemical engineers have discovered a 1,000% difference in the storage capacity of metal-free, water-based battery electrodes.

Fresh insights into how our bodies interact with the microbes living in our guts suggest that a two-drug combination may offer a new way to treat inflammatory bowel diseases such as Crohn's disease and ulcerative colitis.

Scientists have demonstrated that, globally, the association between antibiotic consumption and antimicrobial resistance (AMR) between human and animals goes both ways.

Researchers have developed a new way to produce and shape large, high-quality mirrors that are much thinner than the primary mirrors previously used for telescopes deployed in space. The resulting mirrors are flexible enough to be rolled up and stored compactly inside a launch vehicle and then reshaped after deployment.

A groundbreaking three-year study in the South Pacific has found evidence that ocean warming can trigger outbreaks of 'dinoflagellate-infecting RNA viruses' that attack symbiotic algae inside corals. Coral reef viruses have gained greater attention since being implicated in 2021 as a possible cause of stony coral tissue loss disease that has decimated Florida and Caribbean reefs for almost a decade.

Materials scientists showed that fine-tuning interlayer interactions in a class of 2D polymers can determine the materials' loss or retention of desirable mechanical properties in multilayer or bulk form.

Researchers have discovered, using a recently developed technology, that genetically identical cells within a bacterial community have different functions, with some members behaving more docile and others producing the very toxins that make us feel ill.

Researchers show that rising temperatures in northern regions may damage peatlands: critical ecosystems for storing carbon from the atmosphere -- and could decouple vital processes in microbial support systems.

Wastewater is a more potent environment for antibiotic resistance to evolve than previously known. A study shows that wastewaters have unique characteristics, allowing resistance genes to start their journey from harmless bacteria to those that cause disease.

Researchers have succeeded in developing an E. coli-based 'smart microbe' that secretes therapeutic payloads, including antibodies, into the gut. The genetically modified beneficial strain of bacteria blocks intestinal inflammation in a preclinical model of inflammatory bowel disease and has the potential to treat intestinal-based diseases.

Neuroscientists have developed innovative objectives for light microscopy by using mirrors to produce images. Their design finds correspondence in mirror telescopes used in astronomy on the one hand and the eyes of scallops on the other. The new objectives enable high-resolution imaging of tissues and organs in a much wider variety of immersion media than with conventional microscope lenses.

Shigella bacteria can infect humans but not mice. A team can now explain why. Their findings may explain the multifariousness of a key weapon of our immune system.
